heart valve replacement

I have an enlarged heart and all three valves leak. My cardiologist keeps telling me I am getting closer to surgery. I spent a day and night in the hospital the end of August, straight from the Doctors office to the hospital. I guess my EKG was bad and I had a slow heart beat. Nothing showed up that the cardiologist said was new. He did mention about the heart beat. It is getting worse. I am off two medications and I can hear and feel my heart pounding in my head. One Doctor years ago told me I had good hearing. Yah, right! I am not overweight so losing weight is not needed. Anyone have this surgery? I am not worried about it, but I would like to either get it done so I can get on with my life. What a pain.
